Mechanical principle course is a basic course of mechanical engineering, which mainly introduces the motion law, mechanical principle and design method of mechanical system. In order to study this course effectively, we can adopt the following learning methods:

1. Preview: Read the textbook carefully before class, understand the basic content and key points of the course, and prepare for classroom study.

2. Classroom listening: Listen carefully to the teacher's explanation, actively participate in classroom discussion, and record the key points and difficulties of the teacher's explanation in time.

3. After-class review: review the classroom content in time after class to consolidate what you have learned. You can review it by doing exercises after class and consulting relevant materials.

4. Practice: The course of Mechanical Principles involves a lot of theoretical knowledge, and the understanding of theoretical knowledge can be deepened through practice. You can participate in practical activities such as experimental classes and internships, and apply theoretical knowledge to practical operations.

5. Group discussion: form a study group with classmates to discuss difficult problems in the course, help each other and make progress together.

6. Ask the teacher: Don't be afraid to ask the teacher questions you don't understand. The teacher will patiently answer your questions and help you solve them.

7. Regular summary: summarize the knowledge learned regularly, sort out the knowledge system, and check for leaks.

8. Expand reading: In addition to teaching materials, you can also read some professional books, papers and other materials related to mechanical principles to broaden your knowledge and improve your overall quality.

In a word, to learn the course of Mechanical Principle, we need to master certain learning methods, pay attention to the combination of theory and practice, and constantly improve our professional quality.
